Hello and thank you
What I hear is closer to the "Data" pulses from the controller IC getting
in to the audio. This circuit is complicated and over my head.I was going to
gamble that if I changed the audio out board ( which has a large scale
control IC on board, the problem would go away. Or if I can figure out how
to filter it out it would be ok.
Thanks again, and if anybody has any ideas , please!!!
